Sculpting by Numbers

An approach that allows an unskilled user to sculpt an accurate physical replica of a digital 3D model. Guidance indicating how to adjust a sculpture to match a target 3D shape is projected onto the sculpture itself.

Structural Optimization of 3D Masonry Buildings

An approach to guide architectural forms toward more structurally sound shapes. We define a new measure of structural stability for masonry buildings as well as cables, and derive closed-form derivatives with respect to vertex displacement. We start with a gradient descent tool, then introduce displacement operators and additional objectives.

Algorithms computing minimal-volume OBBs are usually approximations or heuristics that may be far from optimal. The only exact algorithm (by
O'Rourke) is slow and hard to implement. We propose a hybrid method combining genetic and Nelder-Mead algorithms that appears to be faster or more reliable for any accuracy.
